The real question is, once we put up our sulfuric umbrella (assuming that no unforeseen consequences result, like acid rain), what do we do when the sun's current fever goes into remission?

I for one don't want a cloud of noxious, human-created gas floating around over my head. Let's limit that to Massachusetts and Washington, DC, please.
Strike four! You're out.
